Argon arc welding
TIG welding (Tungsten Inert Gas welding), also known as argon arc welding, is a precise and high-quality welding method that uses a non-consumable tungsten electrode and an inert shielding gas, typically argon. This technique is especially suited for welding stainless steel, aluminum, copper, titanium, and other non-ferrous metals.
In TIG welding, an electric arc is created between the tungsten electrode and the workpiece. The heat from the arc melts the metal at the joint, and a filler rod can be added manually if needed. The argon gas flows through the welding torch, protecting the weld area from atmospheric contamination such as oxygen and nitrogen.
Advantages of TIG welding:
- Extremely clean and high-quality welds,
- Very low spatter and no slag,
- Excellent corrosion resistance of joints,
- Ideal for thin materials and delicate components,
- Suitable for all welding positions.
TIG welding is widely used in aerospace, chemical processing, food industry equipment, stainless steel fabrication, and aluminum repair. It requires skill and precision, but the results are strong, visually clean, and highly durable welds. Due to its accuracy and control, TIG is considered one of the most advanced welding processes available today.
